ST. LOUIS (KSDK) - We learned more Monday about a deadly limousine fire that killed five women in California.

Investigators say the vehicle was carrying too many passengers.

We wanted to dig a little deeper into safety and regulations around limos, so we invited Vince Schneider, owner of JED Transportation to join NewsChannel 5 at 5 p.m. to talk about limo safety.

JED is in no way associated with the accident in California, and the cause of the fire has not yet been determined.

Schneider says they have implemented their own safety precautions in addition to regulations. Each vehicle has at least one fire extinguisher in it, but many have two. The fire extinguishers are mounted in places that allow the driver to reach it.

Because the size of the JED Transportation fleet is so large, it is under federal Dept. of Transportation regulations, as well as local regulations.

Schneider says all vehicles must be less than five years old. They try to turn the vehicles every five years to comply with regulations.

He says all of JED Transportation drivers come from a company called Professional Chauffeur, Inc. They must complete a DVD series, which includes workshops and tests.

The drivers are then road tested and complete two sets of training classes. The first is with the lead chauffeur for corporate accounts, who teaches the drivers about airport regulations.

The second is for retail outings, such as proms and weddings, which teaches customer service techniques.
